Recap Challenge

Part of the Practical Frontend section of Coddy's HTML journey. Lesson 11 of 35.

Challenge

Easy

You are given an HTML page for a user profile. Your task is to apply mobile-first design principles to make the page fully responsive. Follow these instructions:

1. Mobile-First Navigation

On larger screens, show the navigation list and hide the menu button.

2. Mobile-First Typography

Create a CSS variable --body-font-size: 16px and apply it to the body. This will be the base font size for small screens.

3. Mobile-First Images

Use the <picture> tag to provide different image sizes for mobile and larger screens.
Use the <source> tag with srcset pointing to a larger image, for example: https://upload.wikimedia.org/wikipedia/commons/1/1f/Woman_1.jpg.
Add media="(min-width: 768px)" to apply it for bigger screens.
Make sure the profile image scales properly depending on the screen width.

4. Mobile-First Forms

Set the width of all input fields and the submit button to 100%, so they take the full width and are easy to tap.

The page should look clean, readable, and user-friendly on both mobile and desktop screens. Apply spacing, alignment, and responsive sizing so everything feels balanced.
